It has been assumed that basic service procedures inherent to the industry, and more

4、 specifically YAMAHA Products, are already known and understood by the users, and have therefore not been restated. WARNING:Failure to follow appropriate service and safety procedures when servicing this product may result in personal injury, destruction of expensive components, and failure of the p

5、roduct to perform as specified. For these reasons, we advise all YAMAHA product owners that any service required should be performed by an authorized YAMAHA Retailer or the appointed service representative. IMPORTANT:The presentation or sale of this manual to any individual or firm does not constitu

6、te authoriza- tion, certification or recognition of any applicable technical capabilities, or establish a principle-agent relationship of any form. The data provided is believed to be accurate and applicable to the unit(s) indicated on the cover. The research, engineering, and service departments of

7、 YAMAHA are continually striving to improve YAMAHA products. Modifications are, therefore, inevitable and specifications are subject to change without notice or obligation to retrofit. Should any discrepancy appear to exist, please contact the distributors Service Division. WARNING:Static discharges

13、he production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (where applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possibly other entities) to cause cancer and/or birth defects or other reprod

When soldering, do not inhale solder fumes or expose eyes to solder/flux vapor! If you come in contact with solder

15、 or components located inside the enclosure of this product, wash your hands before handling food. WARNING: Laser Safety This product contains a laser beam component. This component may emit invisible, as well as visible radiation, which may cause eye damage. To protect your eyes and skin from laser

16、 radiation, the following precautions must be used during servicing of the unit. 1) When testing and/or repairing any component within the product, keep your eyes and skin more than 30 cm away from the laser pick-up unit at all times. Do not stare the laser beam at any time. 2) Do not attempt readju

17、stment, disassemble or repair of the laser pick-up, unless noted elsewhere in this manual. 3) CAUTION: Use of controls, adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. Laser Emitting conditions: 1)When the Top Cover is removed, a

18、nd the POWER SW is turned to the ON position, the laser component will emit a beam for several seconds to detect if a disc is present. During this time (5 - 10 sec.) the laser may radiate through the lens of the laser pick-up unit. Do not attempt any servicing during this period! If no disc is detec

19、ted, the laser will stop emitting the beam. when a disc is set, you will not be exposed to any laser emissions. 2)The laser power level can be adjusted with the VR on pick-up PWB, however, this level has been set by the factory prior to shipping from the factory. Do not adjust this laser level contr

20、ol unless instruction is provided elsewhere in this manual. Adjustment of this control can increase the laser emission level from the device.

25、5/CDC-506 CDC-685/CDC-906 1M Conductive material (sheet) or steel sheet Anti-static wrist strip Grounding for electrostatic breakdown prevention 1. Human body grounding. Use the antistatic wrist strap to discharge the static electricity from your body. 2. Work table grounding. Put a conductive mater

26、ial (sheet) or steel sheet on the area where the optical pickup is placed and ground the sheet. Caution: The static electricity of your clothes will not be grounded through the wrist strap. So take care not to let your clothes touch the optical pickup. Some semiconductor (solid state) devices can be

27、 damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and semiconductor “chip” components. The following techniques should be used to help reduce th

28、e incidence of component damage caused by electro static discharge (ESD). 1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available dischargin

29、g ESD wrist strap, which should be removed for potential shock reasons prior to applying power to the unit under test. 2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to prevent electrostatic charge buildup or expos

30、ure of the assembly. 3. Use only a grounded-tip soldering iron to solder or unsolder ES devices. 4. Use only an anti-static solder removal device. Some solder removal devices not classified as “anti-static (ESD protected)” can generate electrical charge sufficient to damage ES devices. 5. Do not use

31、 freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices. 6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement ES devices are packaged with leads electrically shorted toge

32、ther by conductive foam, aluminum foil or comparable conductive material). 7. Immediately before removing the protective material from the leads of a replacement ES divice, touch the protective material to the chassis or circuit assembly into which the device will be installed. CAUTION: Be sure no p

33、ower is applied to the chassis or circuit, and observe all other safety precautions. 8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can gener

34、ate static electricity (ESD) sufficient to damage an ES device).
